For every 3/4 of an hour Saul studies Spanish, he spends 1/5
1 answer:
Answer & Step-by-step explanation:
The fraction 3/4 can also be written as 0.75. The fraction 1/5 can be written as 0.2. So, we can find the unit rate of the time Saul spends studying French to the time he spends studying Spanish by dividing 0.2 from 0.75.
0.75 ÷ 0.2 = 3.75
So, the unit rate of the time Saul spends studying French to the time he spends studying Spanish is hours.
